FUEL CELL SYSTEM AND METHOD FOR CONTROLLING THE SAME
First Claim
1. A method for controlling a fuel cell system including a fuel cell and a secondary battery for storing output power of the fuel cell,the method comprising the steps of:
- detecting a remaining capacity of the secondary battery;
determining a rate of change of the remaining capacity, where the rate of change is defined as positive when it increases and negative when it decreases; and
changing an operation state of the fuel cell based on the remaining capacity and the rate of change.

Abstract
A method is provided for controlling a fuel cell system including a fuel cell and a secondary battery for storing output power thereof. The method includes the steps of: detecting a remaining capacity of the secondary battery; determining a rate of change of the remaining capacity, where the rate of change is defined as positive when it increases and negative when it decreases; and changing an operation state of the fuel cell based on the remaining capacity and the rate of change. The step of changing the operation state is, for example, a step of switching the operation state between a plurality of power generation modes based on the remaining capacity and the rate of change.
